Learning to be free: smartwatches, mediated negotiation, and children’s everyday agency in Chinese urban families
Abstract This study examines how children’s media agency emerges through everyday practice rather than existing as a pre-given capacity. Drawing on three years of ethnographic fieldwork on children’s smartwatch use in City YT, this study investigates how child–parent relations are continuously negotiated and reconfigured across practices of mobility, sociability, and surveillance.
How Assembly Orientation of an SMPS Inductor Affects Emissions
August 11, 2021 Blog One potential source of emissions is the switching node, referred to as SW on many schematics. The SW node copper can act as an antenna, transmitting the noise generated by fast and efficient high power switching events. This is the main source of emissions for most switching regulators.
Mitigation Strategies for Tricky FM Band Conducted EMI
This article appeared in Microwaves & RF and has been published here with permission. What you’ll learn: What are the drivers of conducted and radiated emissions? Different methods for reducing FM band conducted EMI, which are simple to implement and low cost. Although EMI shields and ferrite clips are often a sought-after EMI solution, they can be expensive, bulky, and sometimes insufficient.
